I got the eflight park 370 and eflite 20amp senorless esc for my piccolo. I wired everything up according to instuctions. I am however having some major issues. When i hook the esc to my reciever first off it seems to come over on the wrong channel. Channels 3 and 4 seem to be reversed but only when this esc is hooked up. Ok thats one problem but the main problem is when i give the motor throttle its gives a high pitched squeal and barley spins. Meanwhile the esc and brushless motor get hot real fast. I am using a 3 cell lipo 1350 mah pack. Elfight is closed til monday so i cant get any help from them. Can any one please HELP!!! My piccolo was flying nicely and i figured brushless would only improve things, unfourtunately with my luck all hell has broken loose.

thanks.
